Hi,
Thanks for the suggestion I tried that, but it still doesn't make any
difference.
I forgot to mention last time, but if I wait a reasonable long period of
time 5 - 10 minutes I can then tune to QAM64 multiplex again.
Thanks
Adam

Hi,
I am having problems getting my FlyDVB-T to lock onto QAM64 signals.
It will occasionally lock onto the multiplex using tzap, but if I
then quit tzap and try again it won't lock, ever. I'm not having this
problem with QAM16 signals and it doesn't appear to be a problem
under Windows (dual boot machine), which makes me suspect the
LinuxDVB drivers.
I am using version 7a0daff8ed2c.
The following is the dump of the kernel messages when the dvb driver
is loaded:

Any help would be much appreicated as I have 2 of these cards in 2
different machines and they both show this problem.
try to set all tuning parameters except frequency and bandwidth to AUTO
I havent heard about problems with QAM64 yet. Which firmware version are
you running?
The reason for your problem might be a too big cystal frequency deviation.
This can depend on the chip temperature. It would be nice if you could
confirm this. Do things change if you operate the PC with an open case or
put the card into a better ventilated slot?
With some driver support, the chip can handle higher frequency offsets.
But it is significant effort to implement this, i can't do this right now.
Best regards
Hartmut
